本文报道了Bi5FeTi3O15(BFTO)纳米纤维/石墨烯(Gr)纳米复合材料(BGR)作为染料敏化太阳能电池的对电极。采用溶胶-凝胶电纺丝技术制备了直径为40~100 nm的BFTO纳米纤维。用X射线衍射仪、扫描电子显微镜和透射电子显微镜对BFTO纳米纤维和BGR纳米复合材料的微观结构和表面形态进行了表征。对BGR-CES的电化学性能进行了全面的表征和研究。与原始的BFTO相比，纳米复合材料具有更大的比表面积和更低的电解液-电极界面转移阻力，对三碘化合物的还原具有明显的电催化性能。最大功率转换效率达到9.56%，远高于纯BFTO Ces的0.22%。
The present study reports Bi5FeTi3O15 (BFTO) nanofibers/graphene (Gr) nanocomposites (BGr) as counter electrodes (CEs) in dye-sensitized solar cells (DSSCs). BFTO nanofibers with diameters of 40–100 nm were fabricated by sol-gel based electrospinning technique. The microstructure and surface morphology of the BFTO nanofibers and the BGr nanocomposites were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The electrochemical performances of BGr CEs were comprehensively characterized and investigated. Compared to pristine BFTO, the nanocomposites have a marked improvement in electrocatalytic performance for the reduction of triiodide because of larger surface area and lower transfer resistance on the electrolyte-electrode interface. The maximum power conversion efficiency has reached 9.56%, which is much larger than that of pure BFTO CEs (0.22%).
